Barrigel® PPRT (Post-Prostatectomy Radiation Therapy) Trial

Conditions

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Barrigel is intended to temporarily position the anterior rectal wall away from the prostate or prostate bed during radiotherapy treatment for prostate cancer and, in creating this space, it is the intent of Barrigel to reduce the radiation dose delivered to the anterior rectum.

Official Title

Randomized Trial of Barrigel® to Increase Distance Between the Rectum and Prostate Bed to Decrease Rectal Dose in Patients Receiving Moderately Hypofractionated Radiation Therapy Who Have Had Recurrence of Prostate Cancer After Prostatectomy

Presence of bilateral hip implants, although unilateral hip implant may be permissible if the implant is MRI compatible and does not produce artifact that interferes with any requirements of the study protocol 21. Subject unable or unwilling to comply with study requirements 22. Any condition that in the investigator's opinion would prevent administration or completion of study therapy
